France warned North Korea on Monday that it would likely face more UN sanctions if it follows through on threats to carry out a nuclear test.

North Korea has reacted angrily to a UN resolution condemning its human rights record and calling on the Security Council to refer Pyongyang to the International Criminal Court for crimes against humanity.

Pyongyang has said it felt no need to refrain from carrying out a nuclear test and North Korea’s top military body warned Sunday of “catastrophic consequences” for supporters of the resolution.

At a UN Security Council debate on non-proliferation, French political counselor Philippe Bertoux recalled that North Korea’s recent threats were a cause of concern.

“I would like to underscore that Pyongyang would, in the event of new provocations, expose itself to additional sanctions from the Security Council,” said Bertoux.

The Security Council imposed sweeping sanctions on North Korea in 2013 after Pyongyang conducted a third nuclear test since 2006.

Those sanctions imposed restrictions on financial transactions and shipping, and targeted the North Korean elite with a tough ban on exports of luxury goods to the reclusive country.

Last week, the US-Korea Institute at Johns Hopkins University said on its 38 North website that new satellite imagery suggested Pyongyang may be firing up a facility for processing weapons-grade plutonium.
